Question about Canon PIXMA MP780 All-In-One InkJet Printer
My Pixma MP780 will not print black ink. I have purchased a new print head and replaced all the cartridges and it is still not printing black. I have run through the maintanence menu several times cleaning and aligning the head but now I am trying to calibrate and it is asking me to change the H value. I do not know where the values are supposto be set. Can anyone help me here. I have them all set at zero right now. Thanks.

0128 is not a recognisable sysmbol Go to the Toshiba web site and the tech Support team- evidently there has been an error in the printed instruct as to the symbol number.

sometimes those measures of ink levels are not very accurate. actually they're usually rather far off... try a new cartridge Usually the easiest solution.

SOURCE: Black 3ek cartridge not printing
I had the same problem before with 3e black ink. It simply does not print too, so what I did if i get to print black and white i will set the characters into dark gray! it looks like draft printing but the things is it can be printed.. I tried to do every instructions available but to fail. I almost dump it till I decided to set it aside for a while. After a week I tried using it again, and it functions well. I guess the printer just want to say, "HEY BUDDY, GIVE ME A LITTLE BREAK!"

Hi it's Gill again. I've been looking around more on the net and I think the problem is our printers need new printheads which I'm told are spare parts easy to change. Hope this helps. Gill

i had the same problem and just repeated the cleaning and testing, eventually the black showed up but took more than a few repetitions

check the cartridge contacts in the printer \
a lot of time they geet covered in ink this will not allow the cartridge to print properly and cause headaches
clean with a baby wipe or a paper towel with soap on it
dry thuoly with hair dryer and try again
